SN74S09D

Inverter Gates Overview

The SN74S09D is a quadruple 2-input positive-AND gate from the Texas Instruments SN54/74S series. It features Schottky-clamped bipolar technology for high-speed operation with a propagation delay of 9 ns. The device provides four independent AND gates in a 14-pin Small Outline (SOIC) package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an open-collector output configuration, allowing for wired-OR connections. The component is rated for commercial temperature ranges from 0°C to +70°C.

Inverter Gates Feature Summary

• Schottky-clamped bipolar technology ensures high switching speeds and reduced power consumption compared to standard TTL.

Inverter Gates Applications

• High-speed digital logic circuits requiring fast AND operations

Inverter Gates Procurement Notes

Verify the specific suffix 'D' indicates the SOIC package variant rather than the standard DIP version. Confirm RoHS compliance status through official manufacturer documentation as requirements vary by production batch. Ensure the open-collector output requirement matches the target circuit design before procurement.

Inverter Gates Selection Notes

Select this component when Schottky speed is required alongside open-collector flexibility. Compare against SN74LS09D for lower cost or SN74ALS09D for different drive characteristics. Verify that the 14-pin SOIC footprint fits the PCB layout constraints and thermal management requirements.

Inverter Gates Part Context

This part belongs to the SN54/74S family, known for high-speed performance using Schottky diodes to prevent transistor saturation. It serves as a bridge between standard TTL and faster ALS technologies, offering improved noise immunity and speed while maintaining compatible logic levels.
